The Movie script is a standard ASCII text file, which contains certain
playback commands.  The following is an example of a movie script:

SCENE ABC
PLAY 1-30

MOVIE
PLAY ABC FOREVER

Although it may seem cryptic at first, the Movie Script is relatively
simple and allows you complete flexibility in creating animations.  The
line reading "SCENE ABC" acts as a label.  "ABC" can be any name you want.
The line reading "PLAY 1-30" specifies that frames 1-30 will be played in
sequence for the animation.  "MOVIE" is another label command that
specifies the main part of the Movie Script.  The line "PLAY ABC FOREVER"
simply jumps to the "SCENE ABC" line and executes the specified "PLAY"
command.  The "FOREVER" specification means that this movie will play in a
continuous`loop`.  Omitting this specification would play the animation
only once.

Other possible variations include:

SCENE ABC
PLAY 1-30
PLAY 29-2

MOVIE
PLAY ABC FOREVER

This would play the animation continuously in a "ping-pong" fashion.  
The`Play`command can be used to specify individual frames such as:

SCENE ABC
PLAY 3
PLAY 6
PLAY 10

MOVIE
PLAY ABC FOREVER

This animation would play frames 3, 6 and 10 continuously.  Finally, you
can specify a specific number of times for the`Play`command as in:

PLAY ABC 5 TIMES

As you can see, the Movie Script provides several possibilities for
animation playback.
